Most practical FPGA designs are limited to finite precision signal processing using fixed-point arithmetic because of the cost and complexity of floating point hardware. While mapping DSP applications onto FPGAs, a DSP algorithm designer, who often develops his applications in MATLAB, must determine the dynamic range and desired precision of input, intermediate and output signals in a design im...

This paper parallelizes the spatial pyramid match kernel (SPK) implementation. SPK is one of the most usable kernel methods, along with support vector machine classifier, with high accuracy in object recognition. MATLAB parallel computing toolbox has been used to parallelize SPK. In this implementation, MATLAB Message Passing Interface (MPI) functions and features included in the toolbox help u...

In an era where accumulating data is easy and storing it inexpensive, feature selection plays a central role in helping to reduce the high-dimensionality of huge amounts of otherwise meaningless data. This report overviews concepts and algorithms of feature selection, surveys existing feature selection algorithms for classification with a categorizing framework based on the complexity: filter, ...

A great deal of interest has been shown in the literature in the development of new Non-Destructive Techniques (NDT). In particular, there is increasing interest in detecting, evaluating and locating cracks as well as the source of the impact causing these cracks. Fuzzy logic was shown to be useful in crack detection, and severity of crack in materials. In this paper Fuzzy logic has been used i...

In this paper, we investigate the proprieties of automatic speaker identification (ASI) to develop a system for voice pathologies detection, where the models do not correspond to different speakers but it corresponds to classes of patients who share the same diagnostic. One essential part in this topic is the database (described later), the samples voices (healthy and pathological) are chosen f...

This paper presents the practical implementation of Phase-Shifting Transformer (PST) model into an Optimal Power Flow (OPF) problem by using the Matlab optimization toolbox. The complexity degree related to the proposed implementation is equivalent to that required by commercial optimization packages for solving optimization models, but with the advantage that Matlab is commonly the available s...

Acknowledgements The production of this Toolbox was made possible by a UK SERC grant on " Genetic Algorithms in Control Systems Engineering " (GR/J17920). Many thanks are due to Hartmut Pohlheim, a visiting researcher from the Technical University Ilmenau, Germany, for the support for real-valued genetic algorithms and his hard work in coding and revising many of the routines in this Toolbox.

This paper presents an open-access Matlab/Simulink-based power system simulation toolbox (MatPSST) for research and education. In MatPSST, dynamic modeling is implemented by Simulink. Only the initialization process coded in Matlab. structure makes full use of Simulink, enabling users to fully rich solvers built-in toolboxes Matlab/Simulink, such as small-signal analysis, without additional pro...
